[Intel-gfx] [PATCH 00/11] drm/i915: Simplify handling of modifiers

[Imre Deak]

This patchset adds a descriptor table for all modifiers used by i915,
which deduplicates the listing of supported modifiers during plane
initialization and during checking for a modifier support on a plane.
This also simplifies getting some modifier attributes like checking
if a plane is a CCS modifier. The motivation is to make it easier to
add and maintain new CCS modifier sets, which will be needed for at
least ADL-P and another upcoming platform.

Tested with igt/kms_plane,kms_ccs on CHV,HSW,TGL,ADLP.
